Measure your crops' temperature

From the drone's radiometric thermal photos, a map of the field in degrees Celsius, with the real distance of each photo.

Drone with a thermal camera over a rice paddy, with the temperature map

A plant short of water closes its stomata, transpires less and warms up. The temperature map reveals water stress before it is visible, along with waterlogging, irrigation that does not reach and leaks from channels and pipes.

Map in °C

A temperature for every pixel

Each thermal photo becomes a map in degrees Celsius calculated with the real distance of the shot, from the drone's laser rangefinder or the flight altitude. The photos are merged into the field map, with a cool-to-hot scale and statistics.

List of thermal surveys

Thermal archive

Every thermal survey in one list

The Temperatures page lists the thermal surveys of every farm with date, fields and values. Each map opens on the field and downloads as GeoTIFF for GIS software.

  • List by farm and field
  • GeoTIFF in degrees Celsius
  • Map also on the field page

How to use it

  1. 1

    Fly with the thermal camera

    Differences are sharper in the hottest hours.

  2. 2

    Upload the photos

    Agronix recognises radiometric photos.

  3. 3

    Read the map

    Hot areas: less transpiration; cool areas: possible waterlogging.

  4. 4

    Check in the field

    Starting from the hottest points.
